Depression causes lack of appetite. The cat will be less active, sleep more, will be aggressive, easily irritable and sometimes extremely vocal. Depression may be caused by loss, lack of attention from the owner, hormonal imbalance or a disease. Depression can be treated with mild antidepressants.
A cat not eating may be ill. However, lack of appetite may indicate an uneasy stomach, stress or even cancer. Loss of appetite can be accompanied by other symptoms which will simplify the diagnosis of the condition. Lack of appetite may go away on its own, but may need treatment, depending on the underlying cause.
